Greddy's stance is if it ain't broke, don't fix it. There's no need in adding variables that aren't necessary.
For a first timer changing the fuel pump on this platform they should dedicate at least an hour and that's if they get the factory sock and o-ring song and dance correct on the first attempt and then there's the pesky gasket to contend with and the cutting of the factory fuel filter from the fuel pressure regulator clip. Any screwup in assembly can lead to a drop in fuel pressure which can be catastrophic.
There are certainly not 5 bolts and it's not a simple plug and play job. There's only 1 bolt, the bolt holding the rear drivers seat down and that's the easiest part of the job.
Personally, if the OP didn't install the fuel pump prior to tuning, such that any incorrect installation would be caught on the dyno, I wouldn't bother with it. I'd go with larger injectors, which require scaling and retuning, before I touch the pump. It's simply not necessary for most base kits on this platform running pump gas.

Direct injection normally runs out of pump before injectors. Whether in tank or HPFP. With there being a duality of injectors, I am sure someone will figure out some slick tuning for them that squeezes the pump out. Also, the dw65c runs a lot smoother than most OEM pumps. Also, better safe than sorry,

I just saw the sending unit etc and it looked really similar. Regardless, you just pull the back seats out and it's right there.
